This invention relates to auxiliary sash for use in conjunction with a primary sash for instance as is used in automobiles. Y

'I'he particular purpose of the invention is to provide a glassed frame that may be introduced into the primary frame for the usual glass of a window or door element of an automobile body or for other locations wherever it is desired to introduce a particular form of glass of a thickness greater than the glass receiving groove of the primary sash.

'I'he usual automobile glass and glass for instance usual in bank -enclosures is inadequate to prevent a bandit from firing through the glass at the driver or other occupant of an automobile or the teller of a bank or oice Where better protection is required for the attendant than is at present possible.

The description of the invention is largely confined to the automobile sash for the doors or windowsV but as this description is practically identical in either structure in respect to the changing of the glass of a sash, the applicability of the invention to other uses than with an autoc.) `mobile will be readily apparent.

'I'he ordinary glass of an automobile is about three-eighths of an inch` thick and the sash for.

the automobile has a groove to receive the peripheral edge of the glass and the frame of the automobile to receive the sash, which is usually of sheet metal, is provided with a runway for the sash.

It has heretofore been required to remove the frame and provide a new frame where glass of materially greater thickness is to be used. It is to avoid this removal or reconstruction of the frame and to utilize the original sash tting therein in which is inserted an auxiliary frame carrying a glass of about one and one-eighth to one and one-half inches in thickness and thus a change may be made from the comparatively thin glass of the usual automobile to the bulletfproof glass of materially greater thickness.

By my auxiliary frame construction, I am able to simply remove the glass from the primary sash of an automobile and insert the auxiliary glassed sash of my invention without changing any other portion of the vehicle body or the frame for the original sash whatever its location may be. This is particularly useful for police cars and the bullet-proof glass is usually provided with gun ports (not forming a particular feature of this invention) through which the occupants 55 of the car may re upon bandits without fear oi (Cl. 18S-64) themselves being injured through penetration of l the glass from the firearms of a bandit.

These objects and other various features of the invention are hereinafter more fully described and claimed, and the preferred form of construction of an auxiliary glassed sash for use in conjunction With a sash for a comparatively thin glass is shown in the accompanying .drawing in Which- Fig. 1 shows the ordinary glassed windshield frame in elevation.

Fig. 2 is an elevation of the same frame in which my auxiliary glassed frame has been introduced.

Fig. 3 is a section taken on line 3 3 of Fig. 1 ,I

Fig. 5 is an enlarged sectional elevation' of a I corner of both the primary and auxiliary sashes showing the manner in which the primary'sash is held united at the corners.

Fig. 6 is a cross section of a modified form of 25 thel auxiliary sash. Y

Fig. '7 is a cross section of another form of the invention.

In Fig. 1, I have shown the usual sash for the glass of an automobile windshield as an instance of the use of the invention in which the lower rail I is curved to t the curve of the lower portion of the frame (not shown) in which it is seated and in Fig. 3 I have shown at 2 a part of the frame in which the primary sash is usually secured. This frame is of the same rectangular form as the primary sash and receives all four rails thereof. This showing in Fig. 2 is merely indicative of such a frame structure. Itis p ointed out that this framestructure 2 and 3 varies considerably with different automobile body forms and it is therefore intended merely to indicate the frame in which the primary sash is tted.V

The primary sash is formed of the-lower rail I, the upper rail 3 and the end railsj and k5 which are mitered at the corners as shown and these frames are of hollow form as is shown in cross section Figs. 3 and 4. At the corners is usually provided in the ordinary automobile frames, an L shaped member 6 which has threaded aperturesk to receive screws l passing through the outer walls 8 and il of the meeting rails. This member 6 holds the frame members in position and by removal o-f the screws 'l on one leg of the L member,

as for instance the leg 6 indicated in dotted lines in Fig. 1 at each end of the lower rail I, this rail may be withdrawn from association with the end rails 4 and 5 and permit removal of the glass ID therein from the bottom. 'Thereafter my improved auxiliary sash and glass may be introduced as the auxiliary sash has a rib; II fitting in the glass groove I2 of the primary sash.

The usual primary rail is shown in section in Fig. 3 and is formed of sheet metal providing a rectangular body fitting the recess provided therefor in the frame 2 and is folded upon itself to provide the sash groove I2 in which the edge of the glass I0 ts and usually a packing element I3 is provided between the glass and the walls of the groove. l

It is obvious that the thick bullet-proof glass, indicated at I4 in Fig. 4, cannot be used with the primary sash, firstly because it is of greater Width than the sash and thus would require a greater width of thefsash and such greater Width of the sash cannot be used with an automobile bodyor in any character of previous installationunless Ythe frame be rebuilt to receive. the wider sash.

Ik therefore have devised an auxiliary sash indir cated'in section at I5 in Fig. 4, which-is of channel form in cross section to receive the edge of the thick glass and with which the usual packing element I6 is associated. I so form the outer peripheral face of ythe auxiliary sash I5 as to provide a rib which may be formed as an integral part ofthe sheetmetal auxiliary sashindic'ated at II in Fig. 4 or may be a bar I Ia secured to the sash I5av as by means of a screw indicated in dot'- ted lines in Fig.` 6. Othershapes may be employed, the essential characteristic being that 'a channel of suflicient width be provided to receive the thicker bullet-proof glass and a rib for engaging in the' glass groove of the primary sash. Usually gun kports I1 are Aprovided in the bulletproof glass which may be of any desired construction.

In Fig. r'7 I have 'shown another form of auxiliary sash. `In this construction the main portion ofthe sash I5b is of channel form in cross section and on this channel is mountedV a comparatively thin sheet metal member 2l) whichr is also of channel form having the edges ofthe sidewalls thereof-inturnedas at `2I over the edge of the wall 22 Vof the channel I5b at each end. VThis member 20 has a central portion on the exterior face of the channel |511 forming aV rib IIb functioning in the same mannerV as the rib I Ia of Fig. 6 or I I of Fig. 4. This rib engages in the primary sash of the windshield or window Y of any character of construction that is originally grooved. to receive a glass fof materially less width than the bullet-proof glass desired Ato be installed therein. In respect to the width ofthe bullet-proof glass, this glassin so-me installations stanceythe greater projection of the glass would preferably beon the exterior face of the Vwindshield rather than projecting interiorly thereof. In such latter case it might possibly interfere with the arrangement'of the frame or parts of the automobile lying adjacent thereto. It is thus to be seen by my improved construction,

that glass of any thickness greater than the Width of the glass groove of the primary sash is capable of receiving may be'readily mounted therein. l

It will be evident that the work of removal of the original glass from the primary sash of an automobile is readily accomplished, one rail being rst removed, the glass I0 then withdrawn from the glass grooves of the sash and replaced by my bullet-proof glass and auxiliary sash of either form shown having a rib for sliding relation with the glass groove of the primary sash.

The installation may be very readily and inexpensively accomplished and without altering the body structure to receive such greater thickness of glass as is required in the formation of a bullet-prooi automobile body. It is to be understood of course that with such bodies the interior of the body with the exception of, the glass is provided with an armor ,plate or other means for prevention of penetration of the bullet fired Such bullet-V bank counter enclosures, and byutilizing the in.-

vention herein described a portion of the primary sash of the original glass may be removed, the glass removed from the remainder of the sash and my glassed sash having a form indicated generally in Figs. 4 and 6 may be introduced thereinto without necessity of reconstructing the orig- ,inal framework of the bank enclosure. In an automobile windshield and other glassed frames Where the glass is not slidable as in'bank enclo-V sures for instance, the main frame 2, the original glass receiving sash 3 and the auxiliary sash having the peripheral outer rib and Wide glass receiving inner edge are mounted together infa non-slidable relationshipwith each of the framesk venclosed by the next outer frame. v The various objects of the invention are -believed to be attained by the'construction described, and it will be evident that the invention materially reduces the cost. of a change from a thin to a thick bullet-proof glass and is readily accomplished with a minimum amount of labor.
